W`INDMILL.

SPECIFICATION forming part of Letters PatentNo. 322,345, dated July 14, 1885.

i Application filed April 22, 1885. (No model.)

pertains to make and use the same, referencel being had to the accompanying drawings, which form a part of this specification, and in Which- Figure l is a front view of my improved windmill. Fig. 2 is a vertical sectional View of the same taken on the line x x in Fig. 1. Fig. 3 is a top View. Fig. 4 is a rear view of the wind-wheel, and Fig.'5 is a detail view of one of the operating-vanes.

The same letters refer to the same parts in all the figures.

This invention relates to windmills; and it has for its object to provide a device of this class which shall possess superior advantages in point of simplicity, durability, and general efficiency. y' With these ends in view it consists in the improved construction,arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A designates a suitably-mounted vertical cylindrical post or tubular shaft, the upper end of which is provided with a cross-piece, B, having transverse braces C C, affording bearings for a longitudinal crank-shaft, D, on the front end of which is mounted a hub, E, to which a series of radial arms, F F, are bolted or otherwise secured. The said arms F F are connected by means of an annular ring, G2, which is bolted or otherwise secured to the front side of the said arms.

G G are the wings or vanes, which are secured to the arms F F by means of hinges H H, attached to the ends of cross-braces I I upon the rear or inner sides vof said wings, which are thus permitted to turn from their normal diagonal position to a position at which their edges shall be presented to the wind, thereby placing the wheel in an inoperative position.

^ l The lower or inner edges of the wings or vanes are provided with laterally-extending brackets J J, in which are mounted swiveled rods K, the inner ends of which are provided with,

are secured to the front sides or faces of the radial arms or spokesF of the wheel on diametrically opposite sides.

The blocks Q Q are provided with slots or openings R R, in which are hinged a pair of arms or bars, S S, which are provided with adjustable Weights T T, tending by centrifugal action to throw the said armsinto a radial position when the wheel revolves rapidly. The said arms are connected by pivoted rods U U with the ring or band M, which latter, when the arms S are thrown into a radial position, turns upon the center pin, O, thereby turning the vanes out ofthe wind and retarding or stopping the motion of the Wheel.

Two of the vanes, which are located on diametricall-y-opposite sides of the wheel, and

which are designated by letters G G', are pro-V vided on their rear sides with pivoted blocks V, to which are attached suitablyconstructed.

springs W W, the inner ends of which are adjusted in recesses X formed in plates Y, which are mounted upon the radial rods or spokes carrying the said wings or vanes G. By the action of these springs the entire set of vanes will be automatically restored to their normal position when the motion of the wheel slackens. The tension of the springbars W may be regulated by means of bolts B2, connecting the opposite ends of the pivoted blocks V with the inner cross-bars I, and having adjusting-nuts C2.

The inner ends of the spring-bars WV are formed with cranks Z, by means of which they may be turned so as to turn the vanes out of IOC ward direction. E is a cord or chain, which is also attached to the said bail B', and which passes over suitablyarranged guides or pulleys F to some point at which it may be conveniently reached and manipulated. It will be seen that by pulling the said rope the bail B is drawn in a 1orward direction, thereby pushing the ring B against the cranks Z,there by turning` the vanes out of the wind.

The rear end of the cross-piece B upon the upper endof the tubular post A carries the tail-vane H', the functions of which are well known.

From the foregoing description, taken-in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood.

The construction is simple andinexpensive, and the wheel may be operated by hand orautomatically in the manner and by the mechanism herein described.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In awindmill,theherein-described Wheel, consisting of a hub having radial arms, the vanes hinged to the said arms, a pair of blocks secured to the front sides of the said arms on diametrically-opposite sides, a cross-bar connecting the said blocks and having a center pin or pivot, a ring hav'ing a cross-bar by which it is mounted to turn and to slide upon the said center pin, swiveled cranks connecting the said ring with the free corners of the vanes, and a pair of centrifugal arms pivoted in the blocks upon the face of the wheel, and connected with the adj Listing-rings by pivoted rods, substantially as and for the purpose herein set forth.

2. The combination of the crank-shaft, the hub having radial arms or spokes, the Vanes hinged to the latter, the adjusting-ring connected with the free corners of the vanes by swiveled cranks, the centrifugal arms connected with the adj usting-ring by pivoted rods, the spring-rods attached to the rear sides of several of the vanes and having cranks at their inner ends, and a ring mounted upon a longitudinally-sliding bail and adapted to bear against the said cranks, substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JOSEPH BURKY.
